Abstract
A circuit arrangement for control of a regulated path and a semiconductor circuit () comprises a control connection, with an input, to which a switching signal () for control of the semiconductor circuit () is applied, an output, to which the control connector of the semiconductor circuit () is coupled, a control circuit () arranged between input and output. The switching signal () may be retained at the current value by means of a hold signal and an analytical circuit (), which measures a voltage corresponding to the voltage across the controlled path and generates the holding signal for the control circuit () for a given duration when the voltage across the controlled path of the semiconductor circuit () has a rise which indicates a switching off of the semiconductor circuit ().
